+**What is ReactiveX ?**
+-------------------
+
+![enter image description here](https://lh3.googleusercontent.com/-i2XiOiLr-u4/WGDnM23c8cI/AAAAAAAAHho/MnkItYDyelofBkilkIM8x99tH__EtHP5gCLcB/s0/Reactive+logo.png "Reactive logo.png")

+
+======
+ **Reactive :**
+Reactive programming is a programming paradigm oriented around data flows and the propagation of change. 
+ Reactive programming is programming with asynchronous data streams.
+
+ **ReactiveX :** 
+	 - Is a library for composing asynchronous and event-based programs by using observable sequences.
+ It extends the observer pattern to support sequences of data and/or events and adds operators that allow you to compose sequences together declaratively while abstracting away concerns about things like low-level threading, synchronization, thread-safety, concurrent data structures, and non-blocking I/O.
+	 - Rx* library family is widely available for many languages and platforms (**.NET**, **Java** , **Scala**, **Clojure**, **JavaScript**, **Ruby**, **Python**, **C++**, **Objective-C/Cocoa**, **Groovy**, etc).
+
+----------
+
+**What is RXAndroid ?**
+-------------------
+ - Extended version from RX-Java to Android .
+ - RXAndroid provides many classes which facilities working with android , like 
+			- **AndroidSchedulers**  for facilitating managing multi-threading.
+			- **AndroidObservable** for facilitating dealing within the Android lifecycle.
+			- **ViewObservable** & **WidgetObservable** for facilitating binding views , user clicks ... ect.
+			
+**How RX concept works ?**
+------------
+ - An Observable performs some action, and publishes the result.
+ - An Observer waits and watches the Observable, and reacts whenever the
+   Observable publishes results.
+ - There are three different changes that can occur on an Observable
+   that the Observer reacts to.
+   These are:
+	 - Publishing a value
+	 - Throwing an error 
+	 - Completed publishing all values

+
+**When I can choose RXAndroid to do some behaviour ?**
+--------------------------
+ - *When we have concurrent tasks , like you would fetch data from Remote connections , database , any background processes .*
+ - *When you would to handle stream of UI actions like : user scrolling , clicks , update UI upon some events .....ect .*
+
+
+**What is the RXAndroid benefits?**
+-----------------------------
+RXAndroid will provide you to deal with below problems in one fell swoop:
+
+ - No standard mechanism to recover from errors.
+ - Lack of control over thread scheduling (unless you like to dig deep).
+ - No obvious way to compose asynchronous operations.
+ - No obvious and hassle-free way of attaching to Context.
+
+
+**Handle Retrofit with RXAndroid**
+-----------------------------
+
+![enter image description here](https://lh3.googleusercontent.com/d2slx7bI7Ivykea1Umfo2mMvZVTnO19ifeuJidyZJB6L3u7rlhwlBtp7tsZgrshWiToqz4pW=s0 "retrofit-reactivex-300x150.png")
+
+ - Add RX to your gradle file 
+
+        compile 'io.reactivex:rxandroid:1.2.1'
+        compile 'io.reactivex:rxjava:1.1.6'
+        compile 'com.squareup.retrofit2:adapter-rxjava:2.0.2'
+
+ - Replace Retrofit Call with Observable .
+		 **From**
+		 ```@GET("topstories/v2/home.json")
+		 Call<NewsModel> fetchNews();```
+         **to**	     	
+	     ```@GET("topstories/v2/home.json")
+     Observable<Response<NewsModel>> fetchNews();```
+
+ - Create  `Observable` 
+	 10. Inform your Observable to emit data in background thread with `subscribeOn(Schedulers.io())` .
+	 11.  Inform your Observable to propagate its stream of data to Main Thread with`observeOn(AndroidSchedulers.mainThread())` .
+	 12. Register your subscriber to current Observable with ` subscribe(mSubscriber)`
+	 ```
+Observable
+        .subscribeOn(Schedulers.io())
+        .observeOn(AndroidSchedulers.mainThread())
+        .subscribe(mSubscriber);
+```
+
+
+	 13. create subscriber
+	 
+	 
+	 ```
+	 Subscriber mSubscriber=new Subscriber<Response<NewsModel>>() {
+            @Override
+            public void onCompleted() { //handle what should you do after Observable complete its emission , like dismiss dialog , build UI .
+                 }
+            @Override
+            public void onError(Throwable e) {
+                //Handle your error
+                 }
+            @Override
+            public void onNext(Response<NewsModel> newsModelResponse) {
+                // handle what should you do after receive each emission from observer , like update progress .... ect .
+                }
+        };
+```
+
+
+**Keep your code clean according to MVP**
+-----------------------------
+ - yes , RXAndroid is easy , powerful , but you should know in which MVP
+          layer you will put it .
+ - for observables which will emit data stream , it has to be in your
+   data layer , and don't inform those observables any thing else like
+   in which thread those will consume , cause it is another
+   responsibility , and according to `Single responsibility principle`
+   in `SOLID (object-oriented design)` , so don't break this concept by
+   mixing every thing due to RXAndroid ease .
